This disclosure relates to low energy communication techniques. According to some embodiments, a wireless transmission may be received by a wireless device. The wireless transmission may include a physical layer (PHY) preamble and PHY data. The PHY preamble may include destination information indicating a destination and length information indicating a length (or duration) of the wireless transmission. The destination and length information may be included prior to a portion of the PHY preamble configured for channel estimation. The wireless device may determine whether the wireless transmission is destined to the wireless device based on the destination information. If the wireless transmission is not destined to the wireless device, the wireless device may drop a remainder of the wireless transmission.
Legal claims defining the scope of protection, as filed with the USPTO.
1. An apparatus comprising: a processor configured to cause a first wireless device to: generate a signal for wireless transmission, the signal comprising: physical layer (PHY) data; and a PHY preamble comprising, within a first signaling field, destination information indicating a destination device to which the wireless transmission is intended, wherein the first signaling field comprises two portions and each respective portion of the two portions is preceded by a respective cyclic prefix, wherein each of the two portions comprises the destination information; and wirelessly transmit the signal.
2. The apparatus of claim 1 , wherein the destination information is useable by a second wireless device to determine whether the signal is or is not destined to the second wireless device and to drop a remainder of the signal upon a determination that the signal is not destined to the second wireless device.
3. The apparatus of claim 1 , wherein the signal comprises an IEEE 802.11 wireless communication signal, wherein the PHY preamble comprises at least a legacy short training field and a second short training field that is distinct from the legacy short training field, wherein the destination information is provided subsequent to the legacy short training field and prior to the second short training field.
4. The apparatus of claim 3 , wherein the second short training field comprises one of: a high throughput short training field or a very high throughput short training field.
5. The apparatus of claim 1 , wherein the PHY preamble further comprises length information, wherein each of the two portions comprises the length information.
6. The apparatus of claim 1 , wherein the destination information comprises at least one of a partial media access control (MAC) address of the destination or a partial association ID (PAID) of the destination.
7. The apparatus of claim 1 , wherein a cyclic prefix structure of the first signaling field is useable to identify a field of the PHY preamble that comprises the destination information.
8. A first wireless device, comprising: a radio; and a processor operably connected to the radio and configured to cause the first wireless device to: generate a signal for wireless transmission, the signal comprising: physical layer (PHY) data; and a PHY preamble comprising, within a first signaling field, destination information indicating a destination device to which the wireless transmission is intended, wherein the first signaling field comprises two portions and each respective portion of the two portions is preceded by a respective cyclic prefix, wherein each of the two portions comprises the destination information; and wirelessly transmit the signal.
9. The first wireless device of claim 8 , wherein the destination information is useable by a second wireless device to determine whether the signal is or is not destined to the second wireless device and to drop a remainder of the signal upon a determination that the signal is not destined to the second wireless device.
10. The first wireless device of claim 8 , wherein the signal comprises an IEEE 802.11 wireless communication signal, wherein the PHY preamble comprises at least a legacy short training field and a second short training field that is distinct from the legacy short training field, wherein the destination information is provided subsequent to the legacy short training field and prior to the second short training field.
11. The first wireless device of claim 10 , wherein the second short training field comprises one of: a high throughput short training field or a very high throughput short training field.
12. The first wireless device of claim 8 , wherein the PHY preamble further comprises length information, wherein a first portion of the first signaling field and a second portion of the first signaling field each of the two portions comprises the length information.
13. The first wireless device of claim 8 , wherein the destination information comprises at least one of a partial media access control (MAC) address of the destination or a partial association ID (PAID) of the destination.
14. The first wireless device of claim 8 , wherein a cyclic prefix structure of the first signaling field is useable to identify a field of the PHY preamble that comprises the destination information.
15. An apparatus comprising: a processor configured to cause a first wireless device to: receive a signal for wireless transmission, the signal comprising: physical layer (PHY) data; and a PHY preamble comprising, within a first signaling field, destination information indicating a destination device to which the wireless transmission is intended, wherein the first signaling field comprises two portions and each respective portion of the two portions is preceded by a respective cyclic prefix, wherein each of the two portions comprises the destination information; determine whether or not the signal is intended for the first wireless device based on the destination information; and drop a remainder of the signal responsive to determining that the signal is not intended for the first wireless device.
16. The apparatus of claim 15 , wherein a cyclic prefix structure of the first signaling field is useable to identify a field of the PHY preamble that comprises the destination information.
17. The apparatus of claim 15 , wherein the signal comprises an IEEE 802.11 wireless communication signal, wherein the PHY preamble comprises at least a legacy short training field and a second short training field that is distinct from the legacy short training field, wherein the destination information is provided subsequent to the legacy short training field and prior to the second short training field.
18. The apparatus of claim 17 , wherein the second short training field comprises one of: a high throughput short training field or a very high throughput short training field.
19. The apparatus of claim 15 , wherein the PHY preamble further comprises length information, wherein a first portion of the first signaling field and a second portion of the first signaling field each of the two portions comprises the length information.
20. The apparatus of claim 15 , wherein the destination information comprises at least one of a partial media access control (MAC) address of the destination or a partial association ID (PAID) of the destination.
